sex 5 days ago & late period

the hubby and I got a little caught up 5 days ago and now I'm officially 2 days late on my period. of course after only a couple days I shouldn't be worried but I am and it's stressing me out to the max. I can barely keep my temper because all I want is to start my period. babies are great but I'd like to wait a little longer if possible lol my husband hasn't brought it up and hasn't been checking if I've started so maybe he's not stressed about it and I shouldn't be either. it's just hard
